The correct answer to how many different ways he can draw is 24.

The radius of the sphere with the given point and the center is √238.

Here we have to find the radius of the sphere.

Given data:

The point on the surface of a sphere is (-4, -6, 10) and the point on the center is (2, 3, -1).

The formula for the radius:

r² = (x2 - x1)² + (y2 - y1)² + (z2 - z1)²

where (x1, y1, z1) = point on the center

(x2, y2, z2) = point on the sphere

Now putting the values we have

r² = (-4-2)² + ( -6-3)² + ( 10 +1)²

  =( -6)² +(- 9)²  + (11)²

  = 36 + 81 + 121

  = 238

r = √238.

Therefore the radius is √ 238.

The absolute maximum and absolute minimum of f(x,y) = 3 + xy -x - 2y is f(0,0) and f(1,1) respectively.

The absolute maximum point is a point where the function obtains its greatest possible value.

And Absolute minimum is a point where the function obtains its least possible value. This is the smallest value that a mathematical function can have over its entire curve.

Given equation is, f(x,y) = 3 + xy - x - 2y

we will check absolute maximum and absolute minimum of f(x,y) at the points (0,0), (1,0), (1,1).  

f(0,0) = 3 + (0)(0) - 0 - 2(0) = 3

f(1,0) = 3 + (1)(0) - 1 - 2 (0) = 2

f(1,1) = 3 + (1)(1) - 1 - 2(1) = 1

Therefore we get absolute maximum at f(0,0) and absolute minimum at f(1,1).

An absolute minimum also called a global minimum, occurs when a point of the function is lower any other point on the function within the function's domain. A local minimum also called relative minimum occurs when a point is lower than the points surrounding it.

Answer: they didnt distribute the 7 to the 4.5

Step-by-step explanation:

when distributing something outside of a parenthesis, you have to distribute it to all terms within the parenthesis, not just the variable

After analyzing the given data we will get to know that all the options mentioned above are true.

A = BUC, B is a singleton set, and A = CU2 if A is the set of all prime numbers, B is the set of all even prime numbers, and C is the set of all odd prime numbers. Therefore, option D - All of the specified - is the answer to this question.

We've got

The entire set of prime numbers is A.

A = {2, 3, 5, 7, 11, 13}

B is a collection of even prime numbers.

B = {2}

C is a collection of all odd prime numbers.

C = {3, 5, 7, 11, 13,}

We are aware that the only even prime number is two. As a result, Set B is a singleton set because it only has one element.

Additionally, if we combine sets B and C, we will obtain set A, which contains all prime numbers.

Thus, we obtain A = B U C.

Since B = 2 is a singleton set, if we have A = B U C, we can also say A = C U 2.

Therefore, each of the aforementioned choices is appropriate.

The radius of each circle is:

Therefore, the side lengths of the triangle are:

Heron's Formula allows us to find the area of a triangle in terms of its side lengths.

[tex]\boxed{\begin{minipage}{8 cm}\underline{Heron's Formula}\\\\$A=\sqrt{s(s-a)(s-b)(s-c)}$\\\\where:\\ \phantom{ww}$\bullet$ $A$ is the area of the triangle. \\ \phantom{ww}$\bullet$ $a, b$ and $c$ are the side lengths of the triangle. \\ \phantom{ww}$\bullet$ $s$ is half the perimeter.\\\end{minipage}}[/tex]

The perimeter of a two-dimensional shape is the distance all the way around the outside. Therefore, half the perimeter of the triangle is:

To calculate the area of the triangle, substitute the sides lengths and the value of s into Heron's formula and solve for A:

The graphical representation of the polynomial function is given by the relation f ( x ) = x² ( x - a )²( x - b )⁴ ( x - c )

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the polynomial equation be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x² ( x - a )²( x - b )⁴ ( x - c )

The factors (x - a), (x - b), and (x - c) indicate that the function has roots at x = a, x = b, and x = c. These roots are of multiplicity 2, 4, and 1 respectively, which means that they are repeated in the factors (x - a)², (x - b)⁴, and (x - c), respectively.

The factor x² indicates that the graph of the function opens upward, since the leading coefficient is positive.

Overall, the graph of this function will have eight "humps" or "bumps" corresponding to its eight roots, and the heights and shapes of these bumps will depend on the values of a, b, and c.

Converges Uniformly

A sequence of functions f n(x); n = 1, 2, 3,…. Is said to be uniformly convergent to f for a set E of values of x, if for each ε > 0, a positive integer N exists such that |f n(x) – f(x)| < ε for n ≥ N and x ∈ E.

A sequence (f n) of functions f n : A → R is uniformly Cauchy

on A if for every ϵ > 0 there exists N ∈ N such that

m, n > N implies that |f m(x) − f n(x)| < ϵ for all x ∈ A.

The key part of the following proof is the argument to show that a pointwise

convergent, uniformly Cauchy sequence converges uniformly.

A sequence (f n) of functions f n : A → R converges uniformly on

A if and only if it is uniformly Cauchy on A.

Suppose that ( f n) converges uniformly to f on A. Then, given ϵ > 0, there

exists N ∈ N such that

|f n(x) − f(x)| < ϵ/2

for all x ∈ A if n > N.

It follows that if m, n > N then

|f m(x) − f n(x)| ≤ |f m(x) − f(x)| + |f(x) − f n(x)| < ϵ for all x ∈ A,

which shows that (f n) is uniformly Cauchy.

Conversely, suppose that (f n) is uniformly Cauchy. Then for each x ∈ A, the

real sequence (f n(x)) is Cauchy, so it converges by the completeness of R. We

define f : A → R by

f(x) = limn→∞

f n(x),

and then f n → f pointwise.

To prove that f n → f uniformly, let ϵ > 0. Since (f n) is uniformly Cauchy,

can choose N ∈ N (depending only on ϵ) such that

|f m(x) − f n(x)| < ϵ /2

for all x ∈ A if m, n > N.

Let n > N and x ∈ A. Then for every m > N we have

|f n(x) − f(x)| ≤ |f n(x) − f m(x)| + |f m(x) − f(x)| < ϵ /2 + |f m(x) − f(x)|.

Since f m(x) → f(x) as m → ∞, we can choose m > N (depending on x, but it

doesn’t matter since m doesn’t appear in the final result) such that

|f m(x) − f(x)| < ϵ/2.

It follows that if n > N, then

|f n(x) − f(x)| < ϵ for all x ∈ A,

Then proves that f n → f uniformly

Alternatively, we can take the limit as m → ∞ in the Cauchy condition to get

for all x ∈ A and n > N that

|f(x) − f n(x)| = lim m→∞

|f m(x) − f n(x)| ≤ ϵ /2< ϵ

B can have a maximum value of 750.

Given info,

y ≤ - 15x + 3000

y ≤ 5x

What is the highest possible value of b in the XY plane if a point with the coordinates (a,b) is found in the system of inequalities above?

The maximum value of b occurs when taking equality.

⇒ - 15x + 3000 = 5x

⇒ - 20x = - 3000

⇒ - 20x = - 3000

⇒ x = 150

Therefore, y = 5 * 150

                    = 750

Hence, the maximum possible value of b = 750

Answer: $1.48

Step-by-step explanation:

find how much each gallon cost

Divide by 4 because 4 quarts equal a gallon

2. 5.92/4=1.48

Therefore each quart equals $1.48,

Hope this helps!
